Book Description
A computer program (codenamed FOREL) has been written which simulates the lift traffic conditions existing in the morning up-peak and evening down-peak period for any specified single- zone office building. The program in its present form is a prototype for more sophisticated systems of lift analysis. On the basis of specified performance criteria, a number of feasible solutions are generated with a full listing of relevant information about each solution. To use the program the operator must supply the following data which is punched onto data cards: BUILDING LENGTH IN FEET; BUILDING WIDTH IN FEET; NUMBER OF FLOORS (ABOVE GROUND); STOREY HEIGHT IN FEET; HEIGHT OF GROUND FLOOR IN FEET; EXPECTED LIFE OF THE BUILDING. Internally are specified: a 5 minute handling capacity in terms of a % of building population (ie. 12%) a maximum value for the average waiting interval both of these figures are supplied for the morning peak period which is regarded as the critical period. On the basis of this information, the program then calculates the number of lifts of a certain size and speed which are required, checking each solution for the above criteria and against the performance during the evening peak period. Output from the program consists of a complete list of all possible, feasible solutions with the following information provided: NUM BER OF LIFT CARS; SIZ E OF LIFT CARS; SPEED OF LIFT CARS; AVERAGE WAITING INTERVAL, & HANDLING CAPACITY for morning and evening peak periods; RETURN TRIP TIME; AREA OCCUPIED BY LIFT WELLS EXPRESSED AS A % OF RENTABLE AREA; GRADE OF SERVICE ASSESSMENT; COST BASED UPON PRESENT WORTH SITUATION. This listing allows full comparison of all solutions. No final decision is made by the computer. The responsibility of this still rests with the designer. In this way, the program remains a design aid and not a design mechanism.

Book Description
Computer Methods for Architects deals with the use of computers in the architecture profession. The text explores where and how computers can and cannot help. The book begins with an explanation of how the majority of the architects around the world were once reluctant to use a computer. It then discusses how some architects improved and advanced the use of computers in the profession. The next part of the book discusses the advantages that a computer can offer an architect, as well as some disadvantages. The next chapter talks about how a computer can handle the files of an entire office. Discussions on the computer's database, proper selection of programs, and simulation techniques are also included in the book. The text finally talks about what the future may hold for computers and architects. This book caters to architects, as it talks about what a person in the field could encounter while using computers.

Book Description
Vertical transportation systems (elevators, lifts, escalators and passenger conveyors) are used in almost all buildings of more than a few stories high. Traffic design and control, namely the movement of people by natural and mechanical means, need to be planned carefully as the costs of under- or over-provision are considerable and changes are not always possible. The subject is covered in four sections. The basic principles of circulation and an introduction to lifts are set out at the beginning, and then traffic design methods are outlined, followed by an examination of analysis and control. The sections are complete in themselves and are presented in depth, with worked examples and case studies as appropriate. The latest analysis techniques are set out, and the book is up-to-date with current technology. The mathematics is simplified wherever possible and copious references are given for further study and examples. The practising vertical transportation engineer involved with the sizing of a vertical transportation installation will find this an excellent and authoritative resource. Other members of the design teams: architects, developers and owners, will find the book a useful reference, and the needs of researchers, lecturers and students of the subject will also be satisfied by this simple presentation of the underlying theory. The engineering aspects, which fall into the areas of manufacturing and production, are not covered, but the practical constraints and considerations are indicated.
